Detailed Description

Meta-optimizer.

This optimizer uses a set of optimizers to applyied sequentially on distinct parameters. The set of optimizers is fully specified by a MetaOptimizerInfos object.

To decrease the optimization time, the precision of the optimizers can be increased progressively: if $\varepsilon$ is the final precision required, one may consider using a precision increment of $\sigma=\log_10(\varepsilon/n)$, where $n$ is the number of progressive steps. During the first step optimization step, the precisions of type 1 and 2 optimizers are set to $10^{\sigma}$, $10^{2\sigma}$ for step 2, ... until precision $10^{n\sigma}=\varepsilon$ at step $n$ and later. This saves some time spending in the first steps of the estimation. The number of steps $n$ is set in the constructor of the optimizer.

This optimizer can be used with numerical derivatives.
